IMPROVEMENT IN METHODS 0F MANUFACTURING TUFTED VARNS.

Specification forming `part of Letters Patent N o. 169, l 39, dated October 26, 1875; application filed September 4, 1875. l

To all whom t may concern:

Be it known that I, HENRY BOTTOMLEY, of Camden, New Jersey, have invented an Iniprovement in the Method of Manufacturing Tufted Yarns, of which the following is a specification The object of my invention is to make a tufted yarn of the peculiar character fully described hereafter, so that the cloth made from the yarn shall have a uniform ground, upon which are interspersed well-defined spots.

The apparatus which may be employed in carrying my invention into effect is illustrated in Figure l of `the accompanying drawing, in which A represents the'- main cylinder of the cardmgengine; B B, the'carding-drums, and D D the usual delivery-rollers. E is an endless' band, carrying a mass of fibers, which are to constitute the tufts in the yarn. As the bers are carried forward on the apron they are seized and converted into tufts by the rapidly-revolving roller c, and these tufts are conveyed by any suitable system ofcard-rollers to one of the carding-drums, B, which must be of. such a character that it will simply lay the tufts on, and not card them into the lap of the main cylinder, so that when the lap, as it leaves the card-cylinder, is converted into roping, the tufts will adhere to the latter, but will not be incorporated or mixed with the fibers of the'lap to any greater extent than is necessary to insure proper adhesion.

It will be observed that this depositing of the tufts onto the lap occurs at a fpoint near the conclusion of the carding operation, so that the peculiarity of the tufted roping may not be neutralized by long-continued carding operations.

On spinning the ropiu gs the same peculiarity will be observedthat is to say, the twisted has this peculiarity, that the groundwork will be of the same uniform color as the body of the yarn, and the spots so well dened as not to detract from this uniformity of the body color to the extent which results from the employment of yarn the tufts of which areincorporated with its fibers.

It should be understood that ready-mad tufts may be placed on the apron in place of an indiscriminate mass of fibers; but in this case, also, care should be taken that the tufts are deposited ou, and not carded to too great an extent into the lap of the main cylinder by the drum B.

I wish it to be understood that I do not claim, broadly, the production of mottled or parti-colored yarn by carding the tufts of liber into the lap of a cardingengine 5 but I claim as my iuvention- The mode or process herein described of producingl the within-described yarn-that is, by causing a card-drum to lay the tufts on, and causethem to adhere to the lap of the main card-cylinder of a carding-engine, and subsequently spinning theropingyas set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
